Thank you! Now zsh works finely. Indeed It is the better patch
for the present practically.
But it is somewhat incomplete. Try this:
% emacs -nw
[type ^Z to suspend emacs]
% bg
% fg
[type ^X^C to terminate emacs]
You will see that the bg command needs a fix, too. The
following is it:

case BIN_WAIT:
+ if (func == BIN_BG) jobtab[job].stat |= STAT_NOSTTY;
if ((stopped = (jobtab[job].stat & STAT_STOPPED)))
makerunning(jobtab + job);
else if (func == BIN_BG) {
By the way, bash, tcsh and the old zsh-2.3.1 do well on the
above example, too. They seem free from the emacs problem
entirely. Moreover, zsh-2.3.1 does not ignore the stty changes
done by a job started in the background. In spite of its many
bugs and shortcomings, the old zsh-2.3.1 seems very robust and
good in this particular respect... *sigh*
